Lo esencial

Winter still hasn't loosened its grip at higher elevations. Conditions remain dynamic as yet another storm rolls through the region.

Problemas de aludes

    Probabilidad
    Possible
    Tamaño
    2–3
    Where cornices exist, they have become unstable should be avoided. Cornices will gain fragile new growth with Saturday night's snowfall.

  • Storm Slabs

    Probabilidad
    Likely
    Tamaño
    1–2
    Fresh storm slabs will form at higher elevations over Saturday night as another storm rolls through with moderate snowfall and southwest winds. Slab thickness and reactivity are likely to increase with elevation.

  • Loose Wet

    Moist new snow at lower elevations will have the tendency to sluff from steep slopes on Sunday. This may occur naturally or with a human trigger.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No new avalanches have been reported, but there have been limited observations lately.Please enter your observations on the Mountain Information Network (MIN). See here for details.

Snowpack Summary

Moderate snowfall and winds will form fresh storm slabs on the surface at higher elevations over Saturday night. Below the new snow, Friday's warm temperatures and sunshine moistened surface snow on most aspects and elevations. New snow will form a variable bond with this surface, with a weaker bond expected at higher elevations and northerly aspects where a surface crust may have formed in advance of new snow accumulations. The mid and lower snowpack are well settled and strong.
